BACKGROUND OF THE INVENTION

The present invention is related to a water outlet tubing structure forfaucets, including a faucet body, a washbowl, and water tubes whereinthe faucet body has a lift rod properly mounted therein, and one or morethan one water inlet pipes with external threads defined thereonprotruding downwards at the bottom side thereof. The water inlet pipesof the faucet body can be directly guided from top to bottom tosequentially pass through thru-holes of the washbowl and coupling slotsof washers before securely registered with screw fittings of the watertubes at the bottom end thereof, and inner threads of fixing nuts arefirmly screwed up to the external threads of the water inlet pipes tosecure the washers tight at one side wall of the washbowl thereby,facilitating an easier and speedier assembly as well as atime/effort-saving processing thereof so as to achieve the economicalefficiency.

Please refer to FIG. 1. A conventional water outlet tubing structure forfaucets is made up of a faucet body 10 having a plurality of couplingholes 11 with internal threads 111 defined therein symmetricallydisposed at the proper positions of the bottom end thereof to engagewith external threads 21 of water inlet pipes 20, a plurality of fixingholes 13 with inner threads 131 defined therein symmetrically disposedat one side of the bottom end thereof to register with outer threads 121of screw bolts 12, and a through hole 14 preset at a proper positionthereon for the location of a lift rod 15 therein. A plurality ofwashers 16 are provided, each having a slot 161 defined thereon for themounting of the water inlet pipes 20 and the lift rod 15 thereinrespectively, and thru-holes 162 symmetrically disposed at properpositions thereon to mate with the screw bolts 12 thereof respectively.The washbowl 30 is equipped with engaging thru-holes 31 properlydisposed thereon for the engagement of the water inlet pipes 20therewith, bolt-passage holes 32 symmetrically disposed at one side forthe registration of the screw bolts 12 therewith, and a rod-passage hole33 properly preset thereon for the location of the lift rod 15 therein.

Please refer to FIG. 2. In assembly, the faucet body 10 is properlylocated on top of the washbowl 30, permitting the coupling holes 11, thefixing holes 13, and the through hole 14 thereof to correspondinglyalign with the engaging thru-holes 31, the bolt-passage holes 32, andthe rod-passage hole 33 of the washbowl 30 respectively. Then, thewashers 16 are mutually overlapped and applied to the bottom of thewashbowl 30, permitting the slot 161 and the thru-hole 162 thereof tocorrespondingly align with the engaging thru-holes 31 and thebolt-passage holes 32 of the washbowl 30 respectively. The water inletpipes 20 are sequentially guided through the slots 161 of the washers16, the engaging thru-holes 31 of the washbowl 30, and the couplingholes 11 of the faucet body 10 respectively, permitting the externalthreads 21 thereof to fixedly engage with the internal threads 111 ofthe coupling holes 11 thereof. Then, the screw bolts 12 are sequentiallyled through the thru-holes 162 of the washers 16, the bolt-passage holes32 of the washbowl 30, and the fixing holes 13 of the faucet body 10,permitting the outer threads 121 thereof to securely register with theinner threads 131 of the fixing holes 13 thereof. Finally, the lift rod15 is sequentially guided through the through hole 14 of the faucet body10, the rod-passage hole 13 of the washbowl 30, and proper position ofthe slots 161 of the washers 16 thereof to complete the assemblythereof.

However, the above conventional water outlet tubing structure forfaucets contains some disadvantages. Most of all, the fixing holes 13,the bolt-passage holes 32, and the thru-holes 162 thereof arerespectively disposed at the faucet body 10, the washbowl 30, and thewashers 16 thereof to mate with the screw bolts 12 thereof so as tosecurely fix the washers 16 onto the underside of the washbowl 30thereby, which is not only uneconomically time-consuming andeffort-wasting in the processing thereof, but also inefficiently tediousand troublesome in the assembly thereof.

Please refer to FIG. 3. A second water outlet tubing structure forfaucets includes a faucet body 10′ properly located on top of a washbowl30′ wherein at one side of the washbowl 30′ is disposed a washer 11′with a coupling slot 111′ defined thereon for a water inlet pipe 20′ tobe guided there-through from bottom to top thereof before the waterinlet pipe 20′ is further led sequentially through the bottom side ofthe washbowl 30′ and the faucet body 10′ respectively and fixedlyscrewed up thereto. At the bottom side of the washbowl 30′ and thefaucet body 10′, and at the proper position of the washer 11′ arerespectively disposed a fixing hole and a thru-hole (without shown inthe diagram) for the engagement of a screw bolt 12′ therewith so as tosecurely fix the washer 11′ thereby.

The second conventional water outlet tubing structure for faucets alsohas some drawbacks. Most of all, at the bottom side of the washbowl 30′and the faucet body 10′, and at the proper position of the washer 11′are respectively provided with the fixing hole and the thru-hole to matewith the screw bolt 12′ so as to firmly secure the washer 11′ onto theunderside of the washbowl 30′ thereby, which is not only uneconomicallytime-consuming and effort-wasting in the processing thereof, but alsoinefficiently tedious and troublesome in the assembly thereof.

Please refer to FIG. 4. A third water outlet tubing structure forfaucets includes a faucet body 10″ properly located on top of a washbowl30″ wherein at the other side wall of the washbowl 30″ is disposed awasher 11″ with a coupling slot 111″ defined thereon for a pair ofsymmetrical water inlet pipes 20″ to be guided there-through from bottomto top thereof before the water inlet pipes 20″ are further ledsequentially through the bottom side of the washbowl 30″ and the faucetbody 10″ and fixedly screwed up thereto. At the preset position of thewashbowl 30″, at the bottom side of the faucet body 10″, and at theproper position of the washer 11″ are respectively disposed a fixinghole and a thru-hole (without shown in the diagram) for the engagementof a screw bolt 12″ therewith so as to securely fix the washer 11″thereby.

The third conventional water outlet tubing structure for faucets is alsofeatured by some disadvantages. Most of all, at the bottom side of thefaucet body 10″, at the proper position of the washbowl 30″ and at thepreset position of the washer 11″ are respectively disposed the fixinghole and the thru-hole to mate with the screw bolt 12″ so as to securethe washer 11″ firmly onto the underside of the washbowl 30″, which isnot only uneconomically time-consuming and effort-wasting in theprocessing, but also inefficiently tedious and troublesome in theassembly thereof.
